MACHINE FOR CUTTING PAPER TUBES.

SPECIFICATION forming part of Letters Patent No. 310,629, dated January 13,

Application liled January 12, 1882. (X model.)

1 0 all whom it may concern.-

Be it known that I, MERRIOK F. WrLsoN, a citizen of the United States, residing at Ohicago, in the county of Cook and State of Illinois, have invented a new and useful Improvementin Machines for Cutting Paper Tubes, of which the following is a specification, reference being had to the accompanying drawings, which form part thereof, and in which-' Figure 1 shows a top or plan view; Fig. 2, an end elevation; Fig. 3, a transverse section taken on the line mm, Fig. 1. Fig. 4 is a front elevation of one of the cutterholders. Fig. 5 is a sectional view of a detail portion of the .5 machine, taken on the line 1 3 Fig. 3.

My invention relates to that class of papcrtube-cutting machines which have mandrels orcylinders, in which the paper tubes are placed or formed, and to which cutting-knives are adjusted to out these paper tubes into lengths suitable for boxes or other purposes, and more especiallyto those machines in which the cutters are mounted on pivoted frames; and it consists, partly, in weighting the frame so that they balance upon the pivots, enabling the operator to operate the knives with very little power.

It further consists in providing the adj ustable stops so that the knives can always be brought just to the surface of the mandrel or cylinder when cutting the paper tubes; and it consists, also, in the lateral adjustment of the pivoted frame, by which the operator is enabled to throw all the knives laterally certain desired distances, enabling him to cut tubes of various lengths, as well as very short tubes, all as hereinafter fully described.

In the accompanying drawings, A is the ordinary frame, made in any desired form, as

0 shown, for holding the operative parts of my machine, as hereinafter described.

13 is the mandrel or cylinder, which holds the paper tubes that are to be out into desired lengths. This mandrel has hearings in the frame A, on which it is made to revolve by any suitable gearing or pulleys, C.

D is a pivoted frame supported upon the shaft E, which has bearings in standards on the frame A. This frame D carries a grooved piece, F. It also carries projecting arms G,

on which adjustable weights H are placed, so that they can be adjusted to counterbalance the grooved'piece F and the cutter-holders which they carry, as hereinafter described. These weights, one or more, as may be required, slide upon the arms G, and are fastened in the desired position by means of setscrews h.

I is the handle with which the operator vibrates the frame D to operate the cutters.

J are cutter-holders, which are secured to the grooved piece F by means of a projecting ledge, K, and set-screws L, the ledge interlocking with a nearly V-shaped longitudinal groove on the lower edge of the piece F, and 6 5 the set-screws entering a longitudinal groove on its upper edge, each cutter-holder embrac ing the grooved piece both above and below, as clearly shown in Fig. 3.

It will be readily seen that by adjusting the set-screws L the cutter-holders can be moved laterally on the grooved piece F, and secured thereto at any desired distance apart.

M are revolving cutters, which revolve in the yokes N, that are secured to the cutterholders J by means of the stem of the yoke O.

P are nuts that serve to adjust the stem 0 of the yokes N, and hold them at any desired position of adjustment of the cutters. The stems O of the yoke N are made in such shape, So as shown in Fig. 5, as not to turn inithe cutter-holders J, but only admit of a vertical adjustment in the cutter-holders by means of the nuts P P.

Q is a set-screw, which serves as a stop, against which the pivoted frame D strikes when. the cutters M are thrown to the mandrel B to cut the tubes, so that the cutters will cut the paper tubes upon the mandrel without cutting the mandrel itself. 9

It will be observed that by vibrating the frame D with its shaft E, to which it is attached, the cutters are thrown in the direction of the arrow toward the mandrel B, and as the mandrel 13 turns in the direction indicated by 9 5 its arrow the force used in cutting the paper tends to throw the cutters toward the mandrel B; but the stop Q prevents them from going in that direction farther than to a certain point. The operator does not have to apply the force required to do the cutting. He only applies to the handle I sufficient force to bring the cutters in contact with the work to be done, and that is but a very little force, because of the adjustable weights H, which are designed just to counterbalance the weight of the cutters and their attachments. shaft E has attached to its end a lever, R,which is pivoted to the frame at S. This lever is designed to give the shaft E, which carries the frame 1), a lateral motion, so as to move all the cutters together laterally.

T is a rack, with suitable pinholes, stops, or notches for holding the lever R at any desired lateral adjustment, and thereby securing the knives at any desired lateral position.

In Figs. 1 and 2 of the drawings the rack is shown provided with projecting stops 1, between which the lever may be locked at any desired angle, the lever being so pivoted as to have vertical play enough to admit of the depressing and lifting necessary for this purpose.

It will be observed that very short tubes can be cut and tubes of any desired length by means of this lateral adjustment of all the cutters. A uniform length of tube can also be secured by the operator moving the lever B uniformly to the same lateral position; or differentlengths can be cut by his moving the lever B to different lateral positions.

U is a spring attached to the shaft-E, to al- The.

ways throw it laterally to what I term its normal condition, when notadjusted laterally out of that position by the lever B.

I do not make any claim to the manner of making the frame A or the mandrel B, or the way in which it is driven. Therefore any suitable frame made in any well-known manner for that purpose may be used.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The pivoted frame D, in combination with the grooved piece F, which carries the cutting apparatus, and the adjustable weights H, arranged to counterbalance the grooved piece and cutting apparatus, substantially as and for the purpose described.

2. The pivoted frame D, for carrying the adjustable cutters, and vertically-adjustable stop Q, combined and operating substantially as specified and shown. I

3. The combination of the fixed frame, the

longitudinally-movable shaft E, the lever R,

fulcrumed on the fixed frame and attached to the shaft, the rack T, and the spring U, substantially as described, for the purpose of laterally adjusting all the cutters at once.
